This article applies to:
E-Prime supports license keys that either connect to your machine's USB port or to a USB port on a server machine (on the same network as your local machine). A failure to abide by the following guidelines generates errors messages such as "The system is in violation of the license agreement" or "The grace period for use without a Copy Protection device has expired."
If your machine already abides by the guidelines below and you still receive such licensing errors, please see LICENSE: E-Prime 3.0 License Violation and Grace Period dialogs  and LICENSE: E-Prime 2.0 License Violation and Grace Period dialogs .
Licensing for E-Studio on a virtual/cloud server
E-Prime license keys require a physical USB port. There must be a way for client machines to access the USB key when using a virtual or cloud server to host a Perpetual Group or Network License (i.e., such as a USB-over-IP converter).
For further information on available third-party solutions, please contact Thales (the key manufacturer) through their Customer Support page https://supportportal.gemalto.com/csm.
Remote access to a Perpetual Group or Network License
Perpetual Group and Network Licenses support remote access by broadcasting the license over an active internet connection. This does not require you to connect to your institution’s network remotely (i.e., through a VPN or similar service) or to use any remote desktop software to remote into your work machine on your institution's network.
Your IT department must decide if this is allowed per your institution’s guidelines. If so, they must configure the server machine's Sentinel ACC settings to broadcast the license to remote client machines. You must then configure your offsite machine's Sentinel ACC settings to search for the Group/Network License key. This requires an active internet connection on your machine and the server machine. You may need to allow communication through firewall and antivirus programs on port 1947 (INFO: Windows Firewall Permissions with E-Prime ).
NOTE: See the section on "Configuring Access to Remote License Managers" in LICENSE: How to Install a Perpetual Group License or a Network License  for more details.
Licensing when remotely connecting to your institution's network
You can access a Perpetual Group/Network license on the network through a VPN (or similar service).
If onsite machines are able to access the Perpetual Group/Network License, but you are not able to access it on your offsite machine via a VPN or similar service, you may need to enable the "Aggressive Search for Remote Licenses" option.
First, navigate to the HASP License Manager Admin Control Center (ACC) at by entering http://localhost:1947 into the address bar of your internet browser of choice. You do not require an active internet connection to access the ACC, only a functional HASP driver. Click "Configuration" among the Options on the left side of the ACC and then select the Access to Remote License Managers tab. The "Aggressive Search for Remote Licenses" checkbox is the third checkbox from the top and is unchecked by default.
NOTE: You may need to allow a few minutes for your machine to find the key.
Users occasionally report issues accessing their E-Prime 3.0 Single User License keys on machines they remote into via remote desktop software. This may vary by your version of Windows and the remote desktop software used. You can work around this issue by having E-Studio open before you remote into the machine with the Single User License key.
